When users visit your website and click the "MySetup Installation" link, they are presented with the option to save or run from that location. If the user selects to run from that location, the Setup.exe upgrades the version of Windows Installer on their computer, if necessary, verifies the digital signature on the installer package, and installs the package on their computer.

There is a digital certificate, Mycert.cer, provided with a private key, Mycert.pvk.

The URL of the hypothetical website a customer would visit to install the package is http://www.blueyonderairlines.com/Products/MySetup/mysetup.html.
